I just checked the Altcoins Season Index data and it remains at 48.

For those who don’t know, this is basically a metric that compares how the main altcoins are performing against Bitcoin over the last 90 days.
CoinMarketCap is the one maintaining this number.

What’s interesting is that 48 is right in the neutral zone.
It’s not a true altcoin season ( that would be 75 or higher ), nor a clear Bitcoin dominance ( that would be below 25 ).
Basically, it means the market is divided — some altcoins outperform Bitcoin, others don’t, depending a lot on the specific sector.

Historically, this is important.
In early 2021, we saw the index above 90, which was when everyone was rotating capital into smaller altcoins and the gains were exponential.
Then came the Bitcoin era with institutional narratives.
But between those transitions, the index would pass through neutral zones like the current one.

What catches my attention is that with possible monetary easing in 2025-2026, you could expect more strength in altcoins.
But the index doesn’t reflect that yet.
Some analysts point out that Bitcoin ETFs have created such a consistent base demand that the standard altcoins need to surpass is much higher than before.

For traders, this means it’s not the time for broad bets.
You need to look sector by sector — infrastructure, Layer 1, DeFi, whatever — because the movement is fragmented.
Correlations between Bitcoin and altcoins remain moderately high, so there’s no clear decoupling yet.

What I need to monitor is whether this index moves decisively.
A sustained move above 60 or below 40 would be a sign that something is changing.
Meanwhile, it’s a market that demands fundamental research, not just following momentum.
The 48 index is basically the market telling you to wait, to analyze carefully before moving.
